This is a simple quick'n'dirty trigger lock which I designed for my Dyson V11, it also works with V10 models.
Just slide it in if needed, the trigger gets pushed automatically and the part should stay in place just so.
Print orientation as it comes from the STL file, PLA or PETG with 20% infill at 0.2mm layer height will be fine
